To all whom it may concern: 1

Be it known that LAIJEXA'NDERS. Srnnn, a citizen of the United Statesresidin at Buffalo, in the county of Erie,-tate'of ew York, haveinvented certain newand useful improvements in Composition Roofing andMethods of Making the Same; and l do hereby declare the following-to bea full, clear, and exact description of the invention, such 8.S'.,-Wlllenable others skilled in the art to which it appertains to make and usethe same.

- My invention is an improvement incomposition roofing and the like,and'i'n methods of makin the same, and relates more especially to t eimpressing of identifying data, as for'instance trademarks and the like,on

the roofing while it is in a warm and plastic condition. i

I An object of the invention is to provide a composition sheet or webhaving'on one face at regular intervals impressions or designs cut inthe said face.

.' Another object of the invention is to provide a method of making suchimpressions on the under face of the web or sheet, in such manner thatwhile the impressions will be clear-cut and of'suficient depth to pre;-vent obliteration in handling they will mark the one face only and willnot in any manner'mar the other face by offsetting the web or sheet orthe like;

' In the drawings- Fgure 1 isa perspective View of the printingandplaten rolls.

Figure 2 is an enlarged transverse section of a part of the printingroll.

In the manufacture of composition rooting, it is desirable to impressdata, as forinstance a trademark, upon the under face, that is that faceof the Web or sheet which will notbe exposed to the weather. It is alsodesirable, though not thought necessary, to make the impressions whilethe roofing is 5 in course of manufacture, that is before it passes fromthe machine on which it 1s made.

At this time the web or sheet is in a warm and plastic condition, andrelatively soft, so that it is difiicult' to impress a mark ofsufiicient depth. to prevent obliteration in to handling; withoutmarri'n the opposite face of the web; lit considerab e pressure is used,that portion of the web containing the impression will be ofiset,presenting an em bossed surface on the opposite face.

lln'order to obtain 'a" clear-cut impression, without any ofisetting ofthat portion of the web containing the impressiomlusa'for example, a-diehaving raised printing'characters of greater height: than the depth ofthe impression desired, and I so limit the movement or this die towardthe web during printin or impressing,-that only a portion of. the epth.ottlie printing characters will enter the material of the web and theblank surface of the die will not contact with the web. Thus theimpression is cut in the web and any displacement of the material islateral and not toward the opposite face. In order to prevent stickingof the material to the die, it keep the surface of thedie and of theroll upon which it is mounted lubricated by any suitable-material, asfor instance soap water, or kerosene.

lln theimanutactureof the composition roofing, a body .Tof felted,material; is provided, as for instance of shredded rags and the like,and this bodyis 1- erssd' in asphaltum of a suitable consistency andsaturated therewith. Une'face .is then faced with pitch, and upon thepitch a mineral in a crushed state is placed, and in laying the roofing,it is this face having the crushed mineral which is to the weather. Thei.- pressions or'designsare on the reverse face, and thesaid desi sor-impressions are made while the finishe web is warm and plastic.

in the-drawings is illustrated one form of mechanism for performing themethod above described.

In this mechanism, the web 1 as it passes from the machine on which it.is formed, is passed between a pair of rolls 2 and 3, the former beinga printing roll, while the latter is a platen roll, and one of the rollsis mounted to yield away from the other, to compensate i'or variousthicknesses of the web, and to prevent injury from lumps of asphalt andthe like which may be upon the web. The printing roll has upon theperipheral surface thereof a series of depressions 4:, the depressionscorresponding in spacing and arrangement to the spacing and arrangementof the impressions desired upon the web. Within each of thesedepressions there is arranged a die 5, the said dies having printingcharacters 6 which extend above the surface of the die in the usualmanner, and these characters have sharp ed es in order that they willcut the web an not merely indent it by displacing the material thereoftoward the opposite face. The characters are of greater height than thedepth of the impression desired, and the blank surface of the die isspaced within the peripheral surface of the roll, so that that portionof the web which receives the impression is engaged only by the printingcharacters, and not by the blank surface of the-die. Thus there is nopressure on the web at this point other than the pressure of theprinting characters themselves and there is no tendency to displace thematerial of the web toward the opposite face. The printing roll may bearranged above or below the web, depending upon the character of thematerial being manufactured. For instance roll roofing is cut with theweather or top side down, and in operating upon this material, therinting roll should be above. In cutting shingles from the web however,the weather side is up and the printing roll should be below the web inorder to impress the designs on the bottom of the web. In either casethe printing roll is lubricated, with any suitable lubricant, as forinstance soap water or kerosene, and in the arrangement shown therinting roll 2 runs in contact with a roll E having a facing 8 of feltor like absorbent material. This facing is soaked with the lubricant, inany suitable manner.

In making the impressions, it is essential that they be alike,regardless of the thickness of the web and of its consistency. If theimpression or design is out too deeply, the web will tear, and if it istoo shallow, it will be obliterated in handling. The arrangement of thedie as above described, with only those portions of the charactersextending beyond the peripheral surface of the roll which actuallypenetrate the web insures that the impressions will be out to the samedepth regardless of the thickness of the web and of its consistency.

I claim: v 1. A method of impressing data on one face of sheets or websof composition material without marring the other face, which consistsin cutting the impression in the material by means of dies having raisedcharacters of greater height than the depth of the cut desired.

neeopae 2. A method of impressing data on one face of warm and plasticsheets or webs of composition material without marring the other face,which consists in cuttin the impression in the material by means 0' dieshaving raised sharp edged characters of greater height than the depthcut desired.

3. A method of impressing data on one face of warm and plastic sheets orwebs of composition material without marring the beyond the peripheralsurface of the roll the depth of the impression desired.

5. A method of impressing data on one face of sheets or webs withoutmarring the otherface, which consists in subjecting the web to uniformpressure except at that point on which the impression is to be made andin making the impression atsuch points while the sheets or webs aresupported on the other face.

6. A method of impressing data on one face of sheets or webs, withoutmarring the other face which consists in cutting such data in thematerial while the sheet or web is subjected to uniform pressure aboutthe impression and on the opposite face from the said impression.

7. A method of impressing data on one face of warm and plastic sheets orwebs, without marring the other face, which'consists in cutting suchdata in the material while the sheet or web is subjected to uniformpressure about the impressionand on the opposite face from the saidimpression and in cutting said impression with raised characterscarrying a suitable lubricant.

8. The method of applying identifying data. designs or the like to theface of sheets of the character described without marring or disturbingthe opposite face of the material. which comprises cutting data or thelike in said face on relatively thin lines or cuts, so as notsubstantially to displace or indent the material of the sheets towardthe other face.

9. The method of applying identifying data. designs or the like to theface of relating data o the like in said face on relatively thin linesby means of a sharp cutting terial, which comprises forming theimpresedge while supporting said sheets on the opsions for the outlinesof such data or the posite face. like by narrow cuts which displace thema- 10 10. The .method of applying identifying terial laterally but notsubstantially toward 5 data, designs or the like to the face of sheetsth her: face of the Sheetof the character described without marring ntestimony whereof I affix my slgnature. or disturbing the opposite faceofthe ma- ALEXANDER S.
